The Extraction and Refining of Metals provides a novel approach to the science and technology of both ferrous and non-ferrous metal production. Rather than the traditional treatment in which one metal at a time is considered, this new approach, which examines several metals at a time, reveals more clearly the versatility and limitations of each of the main types of process. The restrictions imposed on the selection of the process routes by thermodynamic and kinetic factors and by economic and environmental constraints are examined in detail. The conservation of energy and materials is emphasized and illustrated by the description of new and improved extraction methods. The types of mathematical models that are being developed for computer control of production operations are indicated, and worked examples demonstrate relevant thermodynamic and mass balance calculations.
The Book Attempts To Present A Comprehensive View Of Extractive Metallurgy, Especially Principles Of Extractive Metallurgy In A Concise Form. This Is The First Book In This Area Which Attempts To Do It. It Has Been Written In Textbook Style. It Presents The Various Concepts Step By Step, Shows Their Importance, Deals With Elementary Quantitative Formulations, And Illustrates Through Quantitative And Qualitative Informations. The Approach Is Such That Even Undergraduate Students Would Be Able To Follow The Topics Without Much Difficulty And Without Much Of A Background In Specialized Subjects. This Is Considered To Be A Very Useful Approach In This Area Of Technology. Moreover The Inter-Disciplinary Nature Of The Subject Has Been Duely Brought Out.While Teaching Concerned Course(S) In The Undergraduate And Postgraduate Level The Authors Felt The Need Of Such A Book. The Authors Found The Books Available On The Subject Did Not Fulfill The Requirements. No Other Book Was Concerned With All Relevant Concepts. Most Of Them Laid Emphasis Either On Thermodynamic Aspects Or On Discussing Unit Processes. Transport Phenomena Are Dealt With In Entirely Different Books. Reactor Concepts Were Again Lying In Chemical Engineering Texts. The Authors Tried To Harmonize And Synthesize The Concepts In Elementary Terms For Metallurgists.The Present Book Contains A Brief Descriptive Summary Of Some Important Metallurgical Unit Processes. Subsequently It Discusses Not Only Physical Chemistry Of Metallurgical Reactions And Processes But Also Rate Phenomena Including Heat And Mass Transfer, Fluid Flow, Mass And Energy Balance, And Elements Of Reactor Engineering. A Variety Of Scientific And Engineering Aspects Of Unit Processes Have Been Discussed With Stress On The Basic Principles All Throughout. There Is An Attempt To Introduce, As Much As Possible, Quantitative Treatments And Engineering Estimates. The Latter May Often Be Approximate From The Point Of View Of Theory But Yields Results That Are Very Valuable To Both Practicing Metallurgists As Well As Others.
Rather than simply describing the processes and reactions involved in metal extraction, this book concentrates on fundamental principles to give readers an understanding of the possibilities for future developments in this field. It includes a review of the basics of thermodynamics, kinetics and engineering principles that have special importance for extractive metallurgy, to ensure that readers have the background necessary for maximum achievement. The various metallurgical unit processes (such as roasting, reduction, smelting and electrolysis) are illustrated by existing techniques for the extraction of the most common metals. Each chapter includes a bibliography of recommended reading, to aid in further study. The appendices include tables and graphs of thermodynamic qualities for most substances of metallurgical importance; these are ideal for calculating heat (enthalpy) balances and chemical equilibrium constants. SI Units are used consistently throughout the text.
This book covers various metallurgical topics, viz. roasting of sulfide minerals, matte smelting, slag, reduction of oxides and reduction smelting, interfacial phenomena, steelmaking, secondary steelmaking, role of halides in extraction of metals, refining, hydrometallurgy and electrometallurgy. Each chapter is illustrated with appropriate examples of applications of the technique in extraction of some common, reactive, rare or refractory metal together with worked out problems explaining the principle of the operation.
This book starts with an extended introductory treatise on the fundamentals before moving on to a detailed description of the new methods of purification of transition metals and rare earth metals.
Chemical Metallurgy provides an understanding of the fundamental chemical principles and demonstrates the application of these principles to process metallurgy and corrosion protection. The book discusses the fundamental chemical principles involved in metallurgical reactions. Since it is felt that the understanding of quantitative thermodynamics and its application to process metallurgy often prove to be a major problem area for students, example calculations and exercises are included at the end of each section in Chapter 2. The final three chapters deal with the applications of the chemical principles to the extraction and refining of metals, metal melting and recycling, and metallic corrosion. The book is intended as an introductory text for metallurgy students studying for first degrees, TEC higher diplomas and certificates, and Graduateship of the Institution of Metallurgists. It should also be of use to scientists and engineers entering employment in the metallurgical and metal finishing industries or the teaching profession.
An Introduction to Chemical Metallurgy, Second Edition introduces the reader to chemical metallurgy, including its fundamental principles and some of their applications. References in the text to a date and the author of some law or principle of physical chemistry are given for the sake of historical significance. This book is comprised of eight chapters and opens with an overview of thermodynamics, with particular emphasis on the first law of thermodynamics; the expansion of a gas; thermodynamically reversible changes; applications of thermochemistry in metallurgy; and experimental techniques in calorimetry. The following chapters focus on entropy, free energy, and chemical equilibrium; solutions and reaction kinetics; extraction and refining of metals, including refining by preferential oxidation; and corrosion and electrodeposition. Electrochemistry and interfacial phenomena are also explored, along with surface energy and surface tension, electrolytes and electrolysis, and reduction and oxidation potentials. This monograph is written primarily for chemists and metallurgists as well as students embarking on courses in chemical metallurgy.
Extensively revised and updated, this edition provides the broad base of knowledge required by all working in the gold extraction and gold processing industries. It bridges the gap between research and industry by emphasizing practical applications of chemical principles and techniques.
